Sue the T. rex, also known as FMNH PR2081, suffered an avulsion that left a divot and hook-shaped bone spur on "her" right humerus. The divot appears to be located at the origin of the deltoid or teres major muscles. Some experts have hypothesized that gout caused the formation of small patches of eroded bone discovered on Sue's first and second metacarpals. Five other pathologies have been documented in Sue; a pathology on each side of its skull, a twisted and discolored tooth, two pathological tail vertebraein series, and a broken and healed fibula with associated abnormal bone growth.
